Like many of you, I've always struggled with waking up feeling groggy. I learned about 90-minute sleep cycles and wanted a simple way to time my alarms properly.
So I built a free tool website with 5 science-backed sleep calculators:
🌙 Sleep Cycle Calculator - Find the best bedtime or wake time based on 90-minute cycles
📊 Sleep Debt Tracker - Track your weekly sleep deficit
🦁 Chronotype Quiz - Find out if you're a Lion, Bear, Wolf, or Dolphin
⭐ Sleep Quality Score - Get a personalized sleep score out of 100
☕ Caffeine Cutoff Calculator - Know exactly when to stop drinking coffee
No sign-up. No email. Completely free.
I'd love feedback from fellow sleep enthusiasts. What other tools would help you sleep better?
